A carbon susceptor 3 is placed in a quartz reaction pipe 2, the carbon susceptor is heated from the lower side by an infrared lamp 6, and an Si substrate 4 is heated up to 1,100 deg.C. HCl gas is forwarded by 1-2% (by volume ratio) first, and the fouling of the surface of the Si substrate 4 is etched before growth. A temperature is dropped and the substrate is kept at a growth temperature (600-800 deg.C), and the inside of a reaction oven is evacuated by a vacuum pump 7 up to -50Torr. Si(OC2H5)4/H2 is forwarded into a reaction chamber by -1%, the substrate 4 is irradiated by an ultraviolet ray source 5 to promote the decomposition of Si(OC2H5)4, and an Si single crystal is grown on the substrate 4.
